Spray powder for the manufacture of wear resistant and temperature resistant coatings

Spray powder containing aluminum oxide and titanium dioxide for the manufacture of wear resistant and break-out resistant coatings, the spray powder consisting essentially of:

• 50 to 90 weight percent aluminum oxide (Al.sub.2 O.sub.3), 5 to 40 weight percent titanium dioxide (TiO.sub.2), and from 10 up to 30 weight percent of at least one oxide selected from lanthanum oxide (La.sub.2 O.sub.3), a mixture of lanthanum oxide with up to 30 weight percent other oxides of rare earth metals, niobium oxide (Nb.sub.2 O.sub.5), and a mixture of niobium oxide with up to 30 weight percent calcium carbonate (CaCO.sub.3).
